To open/read pre-recorded data I have previously used:

fileID = fopen('filename.txt', 'rt'); line = fgetl(fileID);

to read the text file line by line. However, I need to be able to read data from an instrument connected to a serial port.

i have used

   fid = serial(COMx,baudrate,9600);
   fopen(fid);

Will this work for a live instrument?

fid = serial('COMx', 'baudrate', 9600);

You should also consider setting the Terminiator property.
